During a redshift survey of an infrared complete sample of galaxies recorded by the Infra-Red Astronomical Satellite (IRAS) the authors have identified the IRAS source 00275-2859 as a quasar with a redshift of z = 0.28. The object looks stellar on both blue and red photographic plates, with an apparent optical magnitude J = 17.1 mag. It is a radio source. Its far infrared luminosity is 1.5×1012L_sun;, which exceeds both its optical and radio luminosity. This IRAS source is the second previously unidentified quasar selected through its infrared emission after IRAS source 13349+2438. This suggests that the IRAS data contain a new class of quasars with strong internal reddening that possibly share the violent star formation activity of the most luminous IRAS objects.
